Handle For Sacks And Bags With Revolving Lining

ABSTRACT

Handle for sacks and bags with a rotary lining comprises of two components. Carrying component is longitudinally cut through cylinder ( 1 ) on it has drawn over an elastic and slightly soft rotary lining ( 2 ) of the same aperture ( 3 ). When axial cams ( 7 ) and ( 8 ) that are on the inner surface of the rotary lining set in axial channels ( 9 ) that are incised in radial channel ( 5 ) on cylinder ( 1 ) then the apertures ( 3 ) and ( 6 ) are covered. By revolving, the lining ( 2 ) to a certain angle, the cam ( 8 ) set in channel ( 11 ) and then lining covers i.e. closes the aperture ( 3 ). By revolving the lining ( 2 ) to the other side, covering the aperture ( 3 ) is achieved, and cam ( 7 ) sets in channel ( 10 ). Rotary lining ( 2 ) that slides along the circumference of a cylinder ( 1 ) is axially held on the endings of cylinder by limiters ( 12 ). On the outer surface of rotary lining ( 2 ), recesses ( 4 ) are set symmetrically on both sides of the aperture ( 3 ) in the form of bearings for a thumb for pressing thereof during revolving.

TECHNICAL FIELD OF THE INVENTION

The invention belongs to the field of mechanical engineering and this more precisely to the field of auxiliary devices and assemblies for carrying load in the form of handles. Furthermore, it belongs to the field of protective devices for taking the hold of articles. According to International Patent Classification (IPC) it belongs to B 65 D 33/06—accessories for sacks and bags, and particularly handles thereof.

TECHNICAL SOLUTION

Technical solution resolved hereby is how to safeguard against falling out a handle for carrying bags that is in the form of average bushing that when it is set in position for carrying. Through an aperture is taken hold of bag strips, parcel ropes, bag slits or bucket wires. Upon the temporary laying the load aside, there is a possibility of falling out of the handle through the same aperture. During being held and tied by hands, being under the load the aperture is turned upward but in a released position the handle falls downward so that, through aperture of the strings, the load can be taken out.

STATE-OF-ART

The two main forms of handles for carrying the load are known. The first widely present form is for carrying bags and suitcases in the form of soft plastic or linen handles with clasping band in the overlapping form of a burr strip (the joining adhesive strips). These handles are intended for holding or clasping the bag strips and for soothing the edged narrow suitcase handles. Quite often are sowed of synthetic linen with a soft polyurethane (spongeous) inserted piece. The other form of handles is for heavier loads such as metal pipes in mechanical engineering, in civil engineering auxiliary handles for holding wooden beams and thinner trunks of trees in forestry. They are made of bent wire with lateral hooks, usually two, that are under the handhold. Hooks embrace the load while the handle is achieved above thereof. The part, by means of which it is carried, contains wooden or plastic handle. There should be mentioned that besides these there are magnetic handles for carrying metal parts such as sheet-metals and vacuume ones for carrying smooth plate materials such as glass.

EXPOSITION OF THE SUBJECT OF THE INVENTION

Handhold comprises internal longitudinally cut through cylinder and external lining identically cut through that extends around the circumference of internal part along which can be rotated toward one or the other side and up to the appropriate limiter. Rotation is required when we need to cover longitudinal aperture by external lining and thereby to prevent the handle to drop off the joining string for load in the form of narrow striplike belts, ropes or wire with containers. According to the invention, on the revolving lining, radially arranged are cams and symmetrically along the both sides of longitudinal apertures that fall into the channels on internal cylinder. Channels are used as limiters for setting the medium position when the apertures of a lining and a cylinder are covered and as a position having enough covering to the longitudinal cylinder aperture by turning the lining in another direction. At difference to the winding longitudinal aperture revolvement the lining in a certain angle reliably closes the longitudinal aperture that is in use to draw the load string toward the handhold. Boundary channel and cams make the positions to overlap and cover the longitudinal slots locked in.

DETAILED DESCRIPTION OF THE INVENTION

Figures represent handhold with a rotary lining that comprises of a cylinder 1, whereon lining 2, is axially embedded. Cylinder 1, and lining 2, are longitudinally cut through identically with a vaulted aperture 3 and 6. Aperture 3 is the slightest in the middle whereas symmetrically toward ends it extends. On the cylinder 1, in the middle, from both sides of the aperture 3, radially set is the channel 5, that has hollowed out embeddings 9, 10 and 11, wherein the cams 7 and 8 go into, that are, as protruded parts set in the lining 2. When the aperture 3 is open, i.e. matched to cylinder and on the lining, cams 7 and 8 are set in the embeding 9. When toward one or the other side, the lining 2 is revolved at a certain angle, in comparison to cylinder 1, cam 7 drops in the embedding 9, passing over the aperture 3, and the cam 8, it drops in embedding 10 or 11, provided that it is on the other side. It is enough to swerve the lining toward one or the other side so as to match aperture 3, but the possibility exists on both sides, both on the right and on the left. The edge of aperture 6 on the lining passes the linings in revolving, in as much as it is required to cover the aperture on the cylinder. On the rotary lining 2, there are the recesses 4, that are symmetrically on both sides of aperture 3, as an ease to the material of a thinner wall, and that is at the same time used for easier revolving of the lining as a marked out spot where a thumb rests. Simultaneously the recesses 4, where title or name of the product or firm is noted. Cylinder 1, that carries axially embedded revolving lining 2, is firm with defined distance of the opening of the aperture 3. Longitudinal aperture makes such a figure elastic. Aperture on the lining is marked by 6 and it matches with aperture 3 on the cylinder 1, when the lining is set on the cylinder. The lining is of soft material and elastic enough to leap over the axial limiters 12 that are set on the endings of cylinder 1. It is drawn onto the cylinder between the limiter 12 when it is shrunk according to the required diameter. Besides these limiters, holding the lining axially in relation to the cylinder is achived even by channel 5 wherein permanently led are cams 7 and 8. Embeddings 10 and 11 are of obtuse angle according to the aperture 3 due to its casting in a moulding tool and because of its holding the cams 8, 7 by weak force when the lining is revolved to a certain angle and an acute angle from lower side so as to prevent totally revolving the lining in a full circle, i.e. farther than required revolving and so as to cover the aperture 3. When the handles of a sack or a parcel are thicker than the width of the slot in the middle, the handhold is elastically spread as long as these should drop into the internal cylinder space upon which the slot takes up its normal width. The same happens when the handhold is taken off the bag handles. The function of the revolvment of the lining we can best see at the example of setting the handhold onto a container or a bucket that in its main packaging has a handle made of a thin wire. Such buckets are usually heavy and when carried in hand, we feel pain in hand. Handhold according to the invention slips under the wire handle of the container and before raising it revolves the lining up to the limiter. Hereby, we have achieved that when we set the container aside the handhold remains on the wire.

The Way of Industrial and Other Application of the Invention

The invention is in application in a wide consumption for carrying of different articles and loading. Above all it relates to easier indirect carrying different sacks, bags, parcels, containers, buckets and alike. Hereby, we can embrace a few sacks or bags just as much as can be set in the inside of cylinder at the same time. If the handhold for a time is on the handle of a sack or a container, we can secure it against the dropping off by turning the lining to a certain angle. Cylinder, as the main carrying part, is best to be injected in plastic that has hardness and roughness such as ABS one. Besides, for this accessory, the appropriate material is even polypropylene (PP). The lining has to be elastic and soft so as to be stretchable and drawn over the cylinder, easily. The softness is due to the fact that it is taken by hand. For that purpose, it is recommended to be injected in a less soft polyethylene (PE), about 90 Sh (shore) or some other polyurethane elastomer such as Bergaflex. Handhold is simple for injection moulding in the simple moulding tools. The light weight and ergonomic dimensions make it appropriate for being carried in shopping or carrying loads. Besides personal application it is possible to have wider application as an marketing article in large supermarkets with notes written along the rim thereof, as it is the most appropriate place for the application thereof.
